2013 Bentley Continental GT Speed, shown in Apple Green

Green is seeing a resurgence, not in the typical hunter green of the past, but in lighter and more vivid tones like the Apple Green of the Bentley Continental GT Speed shown here. Still, green only makes up 2 percent of the North American market and 1 percent of the worldwide market.

The eye-catching shade of green on this Bentley is quite uncharacteristic for the ultra-conservative British automaker. The new Speed version of the Continental GT has a more potent 12-cylinder engine and subtle visual differences. The old adage, “If you have to ask how much, then it’s not for you,” applies here. (It starts at $220,725.)
